Maybe it's the glowing aqua blue moonstones, or the crystal clear blue stones, or the shimmery blue aurora borealis that this necklace and earrings showcase. It could also be the faux mabé pearls, which seems a nod to "the sun shinin' so bright" in the same song.

It's probably all of the above. This design is one of Schiaparelli's famous ones from the 1950s, and shares similarities with another famous motif, "Champagne Morning".

The necklace has most of the moonstones and largest stones along the center portion, with graduated sizes of clear crystals, pearls and moonstones scattered along the rest of the strand. The necklace measures about 17" long, with the widest portion about 1" wide. It has a gilt chain, with a ball drop on one end and a hook clasp on the other.

Each earring has a large aqua moonstone cabochon, a trio of large clear crystals and a pair of faux pearls, attended by smaller aurora borealis rounds. Earrings are 1 3/4" x 1 3/4", with clipbacks.

All pieces are marked Schiaparelli in script. In overall very good to excellent condition, save for a tiny chip on the moonstone in one earring, hardly noticeable except from certain angles (see closeups), and does not at all take away from how fabulous this set is. Minimal wear on the goldtone, all the other stones are in great shape.
